響を与えなく、その効果は大きい。Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a method of press-fitting a stator core in which adjacent magnetic poles are connected at a stepped portion from the inner circumferential surface of a part of the ballsche into a stator yoke. This method of manufacturing an induction motor stator is characterized in that after fixing, the connecting portion provided at the stepped portion is removed, and the portion connecting each magnetic pole is stepped from the inner circumferential surface of a part of the ballsche. By providing it in the fallen part, machining cracks and machining distortions that occur when the connecting part is removed do not affect the accuracy of the stator insertion hole, which is highly effective.
